Log Message:
py-hypothesis: updated to 6.21.0

6.21.0 - 2021-09-11

This release introduces strategies for array/tensor libraries adopting the Array \ 
API standard. They are available in the hypothesis.extra.array_api extra, and \ 
work much like the existing strategies for NumPy.

6.20.1 - 2021-09-10

This patch fixes issue 961, where calling given() inline on a bound method would \ 
fail to handle the self argument correctly.

6.20.0 - 2021-09-09

This release allows slices() to generate step=None, and fixes an off-by-one \ 
error where the start index could be equal to size. This works fine for all \ 
Python sequences and Numpy arrays, but is undefined behaviour in the Array API \ 
standard.

6.19.0 - 2021-09-08

This release makes stateful testing more likely to tell you if you do something \ 
unexpected and unsupported:

The return_value health check now applies to rule() and initialize() rules, if \ 
they don’t have target bundles, as well as invariant().
Using a consumes() bundle as a target is deprecated, and will be an error in a \ 
future version.
If existing code triggers these new checks, check for related bugs and \ 
misunderstandings - these patterns never had any effect.

6.18.0 - 2021-09-06

This release teaches from_type() a neat trick: when resolving an \ 
typing.Annotated type, if one of the annotations is a strategy object we use \ 
that as the inferred strategy. For example:

PositiveInt = Annotated[int, st.integers(min_value=1)]
If there are multiple strategies, we use the last outer-most annotation. See \ 
issue 2978 and pull request 3082 for discussion.

Requires Python 3.9 or later for get_type_hints(..., include_extras=False).

6.17.4 - 2021-08-31

This patch makes unique arrays() much more efficient, especially when there are \ 
only a few valid elements - such as for eight-bit integers.

6.17.3 - 2021-08-30

This patch fixes the repr of array_shapes().

6.17.2 - 2021-08-30

This patch wraps some internal helper code in our proxies decorator to prevent \ 
mutations of method docstrings carrying over to other instances of the \ 
respective methods.

6.17.1 - 2021-08-29

This patch moves some internal helper code in preparation for issue 3065. There \ 
is no user-visible change, unless you depended on undocumented internals.

6.17.0 - 2021-08-27

This release adds type annotations to the stateful testing API.

Thanks to Ruben Opdebeeck for this contribution!

6.16.0 - 2021-08-27

This release adds the DrawFn type as a reusable type hint for the draw argument \ 
of @composite functions.

Thanks to Ruben Opdebeeck for this contribution!

6.15.0 - 2021-08-22

This release emits a more useful error message when @given() is applied to a \ 
coroutine function, i.e. one defined using async def.

This was previously only handled by the generic return_value health check, which \ 
doesn’t direct you to use either a custom executor or a library such as \ 
pytest-trio or pytest-asyncio to handle it for you.

6.14.9 - 2021-08-20

This patch fixes a regression in Hypothesis 6.14.8, where from_type() failed to \ 
resolve types which inherit from multiple parametrised generic types, affecting \ 
the returns package.

6.14.8 - 2021-08-16

This patch ensures that registering a strategy for a subclass of a a \ 
parametrised generic type such as class Lines(Sequence[str]): will not \ 
“leak” into unrelated strategies such as st.from_type(Sequence[int]). \ 
Unfortunately this fix requires PEP 560, meaning Python 3.7 or later.

6.14.7 - 2021-08-14

This patch fixes issue 3050, where attrs classes could cause an internal error \ 
in the ghostwriter.

6.14.6 - 2021-08-07

This patch improves the error message for issue 3016, where PEP 585 builtin \ 
generics with self-referential forward-reference strings cannot be resolved to a \ 
strategy by from_type().

6.14.5 - 2021-07-27

This patch fixes hypothesis.strategies._internal.types.is_a_new_type. It was \ 
failing on Python 3.10.0b4, where NewType is a function.

6.14.4 - 2021-07-26

This patch fixes from_type() and register_type_strategy() for typing.NewType on \ 
Python 3.10, which changed the underlying implementation (see bpo-44353 for \ 
details).

6.14.3 - 2021-07-18

This patch updates our autoformatting tools, improving our code style without \ 
any API changes.

6.14.2 - 2021-07-12

This patch ensures that we shorten tracebacks for tests which fail due to \ 
inconsistent data generation between runs (i.e. raise Flaky).

6.14.1 - 2021-07-02

This patch updates some internal type annotations. There is no user-visible change.
